Light-field powered Virtual Reality: Magic Leap secures 542 Million Dollars in Funding from Google and others

Light-field powered Virtual Reality: Magic Leap secures 542 Million Dollars in Funding from Google and others (image: Magic Leap) A rather secretive startup from Hollywood, Florida, recently made headlines for raising a spectacular investment for their vision of the next generation of Virtual Reality. Big names like Google, Qualcomm Ventures, Andreessen Horowitz, and others have put together the sum of 540 million US-Dollars for a company called Magic Leap, but the public isn’t even sure what the company is working on.

The official press release reads: “Magic Leap is going beyond the current perception of mobile computing, augmented reality, and virtual reality. We are transcending all three, and will revolutionize the way people communicate, purchase, learn, share and play.”
…and Magic Leap’s website doesn’t provide many details either.

The company is reportedly working on Dynamic Digitized Lightfield Signals” (Digital Lightfield, in short), a “biomimetic” technology that “respects how we function naturally as humans”. What that means precisely, the company doesn’t explain. However, Technology Review has dug up some interesting patent applications by Magic Leap which may give us a glimpse into what convinced their investors: Continue reading

Nvidia Near-Eye Light Field Display: Background, Design and History [Video]

Nvidia Near-Eye Light Field Display: Binocular OLED-based prototype (Youtube Screenshot) About a year ago, Nvidia presented a novel head-mounted display that is based on light field technology and offers both depth and refocus capability to the human eye. Their so-called Near-Eye Light Field Display was more a proof of concept, but it’s exciting new technology that solves a number of existing problems with stereoscopic virtual reality glasses.

Nvidia researcher Douglas Lanman recently gave a talk at Augmented World Expo (AWE2014), in which he explained the background and evolution of head-mounted displays and the history and design of Nvidia’s near-eye light field display prototypes: Continue reading

Refocus your Eyes: Nvidia presents Near-Eye Light Field Display Prototype

At this year’s SIGGRAPH conference, currently taking place in Anaheim CA, tech blog Engadget spotted an unusual participant in the “Emerging Technologies” section. Douglas Lanman and David Luebke from the research labs at graphics processing specialist Nvidia presented what may be considered a prototype of the future of Virtual Reality: a near-eye light field display.

But what does it do?
Microlens arrays, which are mounted just in front of the high resolution displays, are used to convert pixels to individual light rays, thus creating a light field directly in front of the eye. The viewer is thus able to refocus at multiple depths into the scene.
